analyzer: Fix up -Wunused-variable warning

I've noticed a new
../../gcc/analyzer/kf.cc: In member function ‘virtual void ana::kf_strcasecmp::impl_call_post(const ana::call_details&) const’:
../../gcc/analyzer/kf.cc:2882:12: warning: unused variable ‘lhs_type’ [-Wunused-variable]
warning.
The following patch fixes that.
